February 21, 2026, Llyn Cefni Reservoir and Dam

We visited for the Parkrun, which was cancelled whilst a walkway is fixed (some more weeks, I would expect). You can still access the lake along the disused railway line for part of the way - but not a good surface for running. Then there is a path around the lake with views across the lake and stretches through the woods, lovely, if rather muddy in places following wet weather. In total about 9 km around. Hope to do this again in the Spring with the promise of wild daffodils and perhaps a red squirrel.

Almost endless beach, check tide time to visit Llanddwyn Island as cut off at high tide

Just love this walk. You can park next to the beach but you really are missing out if you don’t walk from the main road through the woods to the beach. Check the tide times if you want to hop over onto the island to see the lighthouse. My dog loves the golden sand but check times of the year for being allowed on the beach.

On the longest day of the year, sunlight flows into the passageway of this Neolithic burial grounds. Bryn Celli Ddu Burial Chamber is one of Anglesey’s most famous prehistoric landmarks, Bryn Celli Ddu (the ‘Mound in the Dark Grove’ in English) is actually two sites in one. In the early Neolithic (New Stone Age) period, a henge (bank and ditch) enclosing a circle of stones was built here, to be replaced later by a chambered tomb beneath a mound measuring up to 85ft/26m in diameter. Inside, a long, narrow passage leads to an octagonal chamber 8 feet/2.4m across, where artefacts such as human bones, arrowheads, and carved stones have been found.

Llyn Cefni Dam During World War II, a water scheme was devised for the town of Llangefni in central Anglesey. It involved water from a local source being pumped to two settling tanks in the Dingle part of the town. From here the water was pumped across the river to a reservoir and water tower, on the site of the present Pennant Estate. These arrangements became redundant with the building of the Cefni Reservoir, which was completed in 1951, but the settling tanks and pumping station survive in Llangefni to this day. The new scheme was designed to supply most of the water needs for the people of Anglesey for the foreseeable future
